We pick f.root-servers.net, one of the 13 root servers (1), and ask it about yahoo.com.mx and learn that mx is delegated to six name servers (2), so we ask x.mx-ns.mx where we learn that yahoo.com.mx is delegated to five name servers, including ns2.yahoo.com (3), so we ask that one and get the following answer:
